    Abstract: An apparatus comprises an input configured to receive electrocardiogram (ECG) data detected by a patient monitoring device, the ECG data containing a physiologic signal and one or more segments of noise within the ECG data. A scrubber comprises a plurality of scrubbing modules each configured to process the ECG data and noise in a manner differing from other scrubbing modules. The scrubber is configured to filter the one or more noise segments that overlap with the physiologic signal, and consolidate the ECG data to eliminate the one or more noise segments that are non-overlapping with the physiologic signal. An output is configured to output scrubbed ECG data.

    Abstract: An EMI/energy dissipating filter for an active implantable medical device (AIMD) is described. The filter comprises a first gold braze hermetically sealing the insulator to a ferrule that is configured to be mounted in an opening in a housing for the AIMD. A lead wire is hermetically sealed in a passageway through the insulator by a second gold braze. A circuit board substrate is disposed adjacent the insulator. A two-terminal chip capacitor disposed adjacent to the circuit board has an active metallization that is electrically connected to the active electrode plates and a ground metallization that is electrically connected to the ground electrode plates of the capacitor. A ground electrical path extends from the ground metallization of the chip capacitor to the ferrule. A conductive ground pin is electrically and mechanically connected to the ferrule. The ground path comprises an internal ground plate disposed within the circuit board substrate. The internal ground plate is electrically connected to the ground metallization of the chip capacitor and to either the ferrule or the ground pin connected to the ferrule. An active electrical path extends between the active metallization of the chip capacitor and the lead wire.

    Abstract: In various examples, a component is for use in an implantable medical device. The component includes a pin including a first material attached to a lead including a second material different from the first material of the pin. At least a portion of the lead includes a channel in which at least a portion of the pin sits, the channel including a channel opening defined at least partially by opposing first and second channel sides extending a channel length. At least a first joint is formed along at least a portion of the first channel side. The first joint includes the second material of the lead deformed to at least partially close the channel opening to retain the pin within the channel to attach the lead to the pin. In some examples, the first material includes molybdenum and the second material includes aluminum.

    Abstract: A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell casing comprises an open-ended ceramic container having a via hole providing an electrically conductive pathway extending through the container. A metal lid closes the open-end of the container. An electrode assembly housed inside the casing comprises an anode current collector deposited on an inner surface of the ceramic container in contact with the electrically conductive pathway in the via hole. An anode active material contacts the current collector and a cathode active material contacts the metal lid. A separator is disposed between the anode and cathode active materials. That way, the electrically conductive pathway serves as a negative terminal, and the lid, electrically isolated from the conductive pathway by the ceramic container, serves as a positive terminal. The negative and positive terminals are configured for electrical connection to a load.

    Abstract: Tantalum powders produced using a tantalum fiber precursor are described. The tantalum fiber precursor is chopped or cut into short lengths having a uniform fiber thickness and favorable aspect ratio. The chopped fibers are formed into a primary powder having a controlled size and shape, narrow/tight particle size distribution, and low impurity level. The primary powder is then agglomerated into an agglomerated powder displaying suitable flowability and pressability such that pellets with good structural integrity and uniform pellet porosity are manufacturable. The pellet is sintered and anodized to a desired formation voltage. The thusly created capacitor anode has a dual morphology or dual porosity provided by a primary porosity of the individual tantalum fibers making up the primary powder and a larger secondary porosity formed between the primary powders agglomerated into the agglomerated powder.

    Abstract: An enhanced RF switchable filtered feedthrough for real-time identification of the electrical and physical integrity of an implanted AIMD lead includes a DOUBLE POLE RF switch disposed on the device side. Additionally, the RF switchable filtered feedthrough can optionally include transient voltage suppressors (TVS) and an MRI mode. In an embodiment, a DOUBLE POLE RF switch selectively disconnects EMI filter capacitors so that an RF test/interrogation signal is sent from the AIMD down into an implanted lead(s). The reflected RF signal is then analyzed to assess implanted lead integrity including lead body anomalies, lead insulation defects, and/or lead conductor defects. The Double Pole switch is configured to be controlled by an AIMD control signal to switch between FIRST and SECOND THROW positions. In the FIRST THROW position a conductive leadwire hermetically sealed to and disposed through an insulator is electrically connected to a filter capacitor, which is then electrically connected to the ferrule of a hermetic feedthrough of an AIMD. In the FIRST THROW position, EMI energy imparted to a body fluid side implanted lead can be diverted to the housing of the AIMD. In the SECOND THROW position the conductive leadwire is electrically connected to an RF source disposed on the device side of the housing of the AIMD. While in the SECOND THROW position, a reflective return signal from the RF source is measured and analyzed to determine if the implanted AIMD lead exhibits any life-threatening performance issues, such as lead body anomalies, lead insulation defects or changes, or even defective, fractured or dislodged lead conductors. In another embodiment, a SINGLE POLE RF switch is configured to disconnect filter capacitors during the delivery of a high-voltage cardioversion shock from an implantable cardioverter defibrillator. Dis-connection of the filter capacitor either reduces or eliminates filter capacitor pulse inrush currents, which allows for the use of standard low-voltage filter capacitors instead of larger and more expensive high-voltage pulse rated filter capacitors. Dis-connection of the filter capacitor also allows for an RF interrogation pulse to be applied to the implanted lead in real-time (for example, pre-set intervals throughout the day).
